I love these photos of John Lennon riding a rod brake Raleigh bike:
While I am not certain that this bike is a Raleigh DL-1, it certainly appears to be one... or two. These are two different bikes! One has blackout handlebars that are set higher than the chrome handlebars in the other photo. Same photoshoot though? rising70's Photostream on flickr is where I found them, and it is indicated there that these images were from the making of Magical Mystery Tour.
